    testing residential a/c's in cold outside temperature or in rain

    Thank you for your info. I work for a HVAC company and do a lot of a/c tuneups in the spring. With the cold weather I do not feel comfortable saying that the a/c is properly charged espicially in cap tube systems. I do not like recieving call backs for any of my jobs.

    testing residential a/c's in cold outside temperature or in rain

    What is the proper way to test residential air-conditoners for proper charge in cold outdoor air temperatures below 65 degrees. Also can you test for proper charge in the rain.
